Stefan is amazing! We have bought 2 houses through him and sold 1. He is always available and is always looking for your best interest, not his bottom dollar. He always told us the pros of cons of every house, including the one we put an offer on. We highly recommend him and have referred numerous friends to him already. Give him a call, you won’t be disappointed!

Andrew & Monica

Stefan helped us buy and sell a home. We have dealt with many realtors over the years, but have never worked with one as open, professional, trust-worthy, and productive as Stefan. We had a great experience with him and he made us feel like we were his only clients. We recommend him without reservation.
